8700 Series Shock Sub

Shock and vibration are effectively and efficiently absorbed through a series of field replaceable shock elements, resulting in increased drilling rates and bit life, reduced drilling machine maintenance and improved operator comfort.

The 8700 Series shock sub has been designed and proven to significantly reduce axial and torsional vibration between the rotary head and drill string.

Rebuild kits are available and the only tools needed to replace the shock absorption units are sockets, screwdrivers and a pry bar. Replacement can be accomplished quickly and the shock sub is returned to service in a timely manner.

The following items should be taken into account before determining a shock sub size:

  1. Axial Load
  2. Bit Size/Type
  3. Pipe OD and Wall Thickness
  4. Ground Formation
  5. Angle or Vertical Drilling
  6. Compressor Size/Air Pressure
  7. RPM
  8. Carousel present
  9. Any overall length restrictions/OD restrictions
